Widepac Hydration with Sawyer Mini Filter.

No fiddling with pumps and filters and chemicals. The new Widepac with inline Sawyer filter lets you re-fill your SOURCE from any creek, river, well, lake or pond and be sure to drink clean water. Unless you're in the desert, this also means: carrying less water, as you are free to refill on the trail!

Sawyer Mini-Filter: How it works
As water passes through the side walls of the filter micro-fibrous tubes, harmful bacteria and protozoa are trapped in the outer walls so you can be confident your water is safe to drink

Long lasting
Filter up to 100,000 gallons from freshwater lakes, rivers or streams. Sawyer filters are so robust, they can be backwashed and reused over and over. No replacement cartridges needed.
